The Type 83 is a 152 mm self-propelled howitzer used by the People's Liberation Army of China.

Key Information

This self-propelled gun system was developed by Factory 674 (Harbin First Machinery Building Group Ltd) and based on a tracked chassis. The project's development started in the late 1970s and the prototype was completed in February 1980, followed by a second in 1981. Production was authorized in 1983 under the designation Type 83. The first production run started in May 1983 and the first public display was on 1 October 1984.[1] This self-propelled gun is similar to the 2S3, with a modified version of the Type 66 gun and a Type 321 utility tracked chassis and is the first modern self-propelled gun in service with the People's Liberation Army. Production ended in 1990, after 780 examples were built. Manufacturing also involved factory 5318 (artillery), 298 (aiming), 754 and 843.[1]

Unlike the U.S. M109 howitzer, this self-propelled gun is made from steel and not aluminum alloy. It has six wheels on each side with the engine is in the forward hull. There is stowage for 30 shells, included a Chinese version of the Krasnopol laser ammunition. The elevation is 0-62° giving a range of 17 km. There is also base-bleed ammunition with improved range, cluster and fragmentation projectiles. A secondary weapon, a 12.7 mm machine gun, is also mounted on the turret. The engine is a 520 hp (382 kW) WR4B-12V150LB four-stroke, liquid-cooled diesel engine. The maximum speed is 55 km/h and range 450 km.[1]

The typical Chinese artillery regiment (one for each armoured division) has 18 SPG organized as one battalion with three batteries. Not long after entering service it was determined to be obsolescent and China started to develop new systems, like the PLZ-45 (mainly for international market) and the real Type 83's replacement, the PLZ-05.

The Type 83 (SPH), designated PLZ-83, is a tracked 152 mm artillery system developed by China's 674 Factory () for the (PLA) and entering service in the mid-1980s. Weighing 30 tons with a of five, it mounts a 152 mm L/35 capable of firing standard 152 mm ammunition at a maximum range of 17.2 km, carrying 30 rounds and achieving a up to 5 rounds per minute. Powered by a 520 hp , the vehicle reaches a top road speed of 55 km/h and an operational range of 450 km, providing mobile fire support at and division levels with basic ballistic protection and secondary armament including a 12.7 mm anti-aircraft . Development of the Type 83 began in 1979 as a response to the PLA's need for modern , drawing design influences from the Soviet while incorporating indigenous components for compatibility with existing 152 mm towed systems like the Type 66. A prototype was completed in 1980, with production authorized in 1983 and running until 1990, resulting in approximately 78 units manufactured before the program ended. The system first appeared publicly during 's National Day parade on October 1, 1984, and features semi-automatic loading, capabilities, and compatibility with conventional high-explosive, rocket-assisted, and guided projectiles such as the Krasnopol. Although largely superseded by the more advanced in the 2000s, the Type 83 remains in limited PLA service or storage as of the late 2010s, underscoring 's early efforts to modernize its forces during the era. Its design emphasizes reliability in varied terrain, with and a low-profile turret for enhanced survivability in combat. No exports have been recorded, keeping the platform exclusive to Chinese forces.

Development

Origins

In the late 1970s, the (PLA) recognized the need for enhanced mobile artillery to support its mechanized forces amid escalating border tensions, particularly following the 1979 , which exposed deficiencies in rapid artillery deployment and integration with armored units during the late era. This drive for modernization was part of broader PLA reforms under , emphasizing professionalization and technological upgrades to counter regional threats from Soviet-aligned neighbors. The Type 83 self-propelled howitzer project drew significant influence from Soviet designs, particularly the 152mm self-propelled howitzer. This approach allowed the PLA to leapfrog its reliance on towed systems, incorporating proven tracked mobility concepts while aligning with domestic production capabilities. Development was formally initiated in 1979 by Factory 674 (now part of the Harbin First Machinery Building Group) in , Province, under the Ministry of Ordnance Industry, with the first prototype completed in February 1980 and a second refined version in July 1981. Key design objectives included compatibility with standard 152mm ammunition for logistical simplicity, superior cross-country mobility over existing towed howitzers to enable rapid repositioning in mechanized operations, and seamless integration into PLA battalions for warfare. These goals addressed the PLA's strategic shift toward a more agile force structure capable of sustaining offensive operations in diverse terrains.

Production

Following the completion of prototype testing in 1982, the design of the Type 83 SPH was finalized in 1983, enabling the initiation of serial production at Factory 674 in . Serial production of the Type 83 SPH occurred from 1983 to 1990, with approximately 78 units constructed to equip artillery formations. Manufacturing also involved factories 5318 (artillery), 298 (aiming), 754, and 843. NORINCO provided oversight for the manufacturing effort, including evaluations for export potential, though no international sales were realized. Initial deliveries to PLA artillery units began in 1984, positioning the Type 83 as the first indigenously developed Chinese 152mm self-propelled howitzer.

Design

Chassis and mobility

The Type 83 self-propelled howitzer employs a based on a modified Type 321 utility vehicle design, incorporating a system for enhanced stability and six double-tired road wheels per side. The running gear features a front-mounted drive , rear idler, and three track return rollers per side, enabling reliable traversal over rough terrain. Propulsion is provided by a front-mounted WR4B-12V150LB 12-cylinder, liquid-cooled, four-stroke producing 520 horsepower (382 kW), which contributes to balanced weight distribution across the hull. The vehicle's dimensions measure 9.8 meters in overall length, 3.24 meters in width, and 3.5 meters in height, with a combat weight of 27,215 kg (30 tons). On-road performance reaches a maximum speed of 55 km/h, supported by an operational range of 450 km. Cross-country mobility includes the ability to climb a 30% , cross a 2.7-meter , negotiate a 70 cm vertical step, and ford water depths up to 1.3 meters without preparation.

Armament

The primary armament of the Type 83 self-propelled howitzer (SPH) is a Type 66 L/29 152 mm rifled gun-howitzer mounted in a turret, derived from the towed Type 66 howitzer and featuring a muzzle brake and fume extractor for enhanced firing stability and crew safety. The gun provides full 360-degree powered traverse and an elevation range of -5° to +65°, enabling flexible targeting in various terrains while supporting indirect fire missions. It achieves a maximum rate of fire of 4-5 rounds per minute in burst mode, with a practical sustained rate lower to manage barrel wear, and carries 30 rounds of 152 mm ammunition internally. Using standard high-explosive fragmentation (HE-FRAG) shells, the effective range reaches 17,230 meters, establishing its role in medium-range artillery support. For secondary armament, the Type 83 mounts a single 12.7 mm Type 54 on a at the commander's hatch for anti-aircraft and close-range defense, supplied with 650 rounds of . An optional Type 69 40 mm launcher is stored inside the turret for crew use against close threats, enhancing self-defense capabilities without integrating into the primary . The system is compatible with all standard 152 mm separate-loading rounds, including high-explosive fragmentation, base-bleed extended-range variants for improved ballistics, cluster munitions, and Chinese-developed laser-guided projectiles akin to the Russian Krasnopol for precision strikes at ranges up to 20 km. This ammunition versatility allows the Type 83 to adapt to conventional and guided fire roles, prioritizing accuracy in modern conflicts.

Protection and crew

The Type 83 self-propelled howitzer is operated by a of five, consisting of a , gunner, two loaders, and . The is positioned at the front left of the hull, while the , gunner, and loaders occupy the rear-mounted turret, enabling centralized control of the weapon system from a compact fighting compartment. The vehicle's protection relies on basic steel armor plating, which provides defense against small-arms fire and shell fragments but offers no significant resistance to heavy anti-tank munitions. Angled turret faces enhance ballistic deflection, and the overall design prioritizes mobility over heavy armor, contributing to the vehicle's approximate 30-ton combat weight. systems are integrated in the engine, fighting, and driving compartments to mitigate internal hazards. Night vision equipment, including passive periscopes for the driver and image intensification for the gunner, supports low-light operations. The incorporates radio-relayed computing for precise support, integrating targeting data to coordinate with forward observers. storage is located in the rear of the turret, accommodating up to 30 rounds of 152 mm projectiles in ready racks, with semi-automatic loading mechanisms facilitating a up to 4-5 rounds per minute. Provisions for rapid reloading include large rear doors on the turret for external resupply, while crew escape is enabled by roof-mounted hatches and side access panels.

Service

Introduction and deployment

The Type 83 self-propelled howitzer entered service with the (PLA) in 1984 as a key element of the service's artillery modernization efforts, aimed at enhancing mobile fire support for and armored units during the 1980s. This introduction represented the PLA's first domestically produced modern self-propelled system, transitioning from towed guns to more responsive tracked platforms capable of accompanying mechanized forces in dynamic operations. Within the PLA structure, the Type 83 was integrated into artillery battalions assigned to mechanized divisions, where it provided indirect fire support in coordination with ground maneuvers. Its operational doctrine emphasized rapid repositioning—often termed "shoot-and-scoot"—to deliver salvos and then relocate quickly, minimizing vulnerability to enemy counter-battery fire and enabling sustained battlefield mobility. Production was limited to approximately 78 units between 1983 and 1990, resulting in selective equipping of priority mechanized divisions rather than widespread adoption across the force. No instances of the Type 83's combat deployment in major conflicts have been recorded, with its service primarily involving training and exercises. The system began phasing out in the late and early amid advancing PLA artillery capabilities, deemed obsolete by the introduction of successors like the in 2008. As of 2025, remaining Type 83 units are confined to reserve storage or training roles, supporting doctrinal familiarization rather than active frontline duties.

Derivatives

The Type 83 self-propelled howitzer chassis has been adapted for a 130mm self-propelled gun variant, primarily intended for export markets to provide lighter artillery support with enhanced mechanized coordination. This version, known as the Type 59 130mm crawler self-propelled cannon, modifies the Type 59-1 towed gun barrel on the Type 83's Type 321 chassis, achieving a maximum of 8-10 rounds per minute and a range of up to 30 km with extended-range full-bore base-bleed high-explosive projectiles. Developed in the , it was not adopted for domestic use due to redundancy with the standard 152mm Type 83 but offered good cross-country mobility and rapid repositioning for supporting motorized troops. Engineering vehicles derived from the Type 83 platform enhance battlefield mobility and obstacle breaching. The Type GJW320 tracked trench-digging machine utilizes the Type 83's and hull to create defensive positions, improving unit survivability in contested environments by enabling quick excavation of trenches for and vehicles. Complementing this, the Type 462 425mm mine-clearing mounts a two-round system on the Type 83 to propel submunitions for rapid minefield neutralization, allowing armored formations to advance through contaminated areas with minimal delay. These adaptations, including the carrier for the Type 762 425mm rocket system, leverage the platform's proven tracked mobility for non-combat engineering roles. An anti-tank derivative, the Type 89 (also designated PTZ-89) 120mm self-propelled gun, employs the same Type 321 chassis from the Type 83 to mount a high-pressure gun with a of approximately 1,800 m/s, designed to engage armored threats like Soviet tanks. Development began in the early 1980s in response to advanced Soviet tanks like the , with prototypes tested in 1984 and initial production deliveries starting in 1989, totaling approximately 100 units equipped to anti-tank battalions in northern army groups. The system provided indirect fire support against vehicles until its retirement in 2015 in favor of guided missiles and attack helicopters. The Type 83 influenced successor systems, particularly through the transition to the more advanced 155mm self-propelled howitzer, adopted by the in 2008 as a direct replacement for the aging Type 83. The incorporates modern fire control and longer-range capabilities while retaining lessons from the Type 83's , contributing to the evolution of Chinese artillery toward NATO-standard 155mm calibers and improved automation. This shift rendered the Type 83 obsolete for frontline service but ensured its foundational role in subsequent designs like the PLZ-07 and PLZ-52 variants.
